Title: Stentless bioprosthetic heart valve with coronary protuberances
Inventor: NGUYEN-THIEN-NHON DIANA
IPC: A61F2/24
Filed: 1998-12-11
Abstract: A stentless aortic bioprosthesis having patent, non-ligated coronary artery segments extending therefrom, and methods for surgical replacement of aortic and/or non-aortic (e.g., pulmonary) heart valves with such stentless aortic bioprosthesis. The presence of the patent, non-ligated coronary segments facilitates end to end anastomosis of the patient's native coronary arteries and/or existing coronary artery bypass grafts to the coronary segments of the bioprosthesis even when such native coronary arteries (or coronary grafts) arc too short to reach the wall of the aortic segment of the bioprosthesis. The presence of such patent, non-ligated coronary segments also eliminates the need for removal of a "button" or segment of the native aorta in connection with the native coronary artery segments prior to implantation of the bioprosthesis, and is thus advantageous for patient's whose ascending aorta is diseased or otherwise compromised.

In one embodiment, data is transmitted at a faster than real time rate and accumulated in a buffer (235, 240) at a receiver. The user can play a current track or skip to subsequent or earlier tracks. In another embodiment, two or more programming service streams (900, 930) (i.e., user channels) are communicated such that a user can move directly from a current track to the beginning of a track of another stream. In another embodiment, tiers of service levels are provided so that paying subscribers can bypass some or all of the commercial messages, while non-paying subscribers can not bypass the commercials. Replacement programming may be transmitted in a portion of the bandwidth of the free service. At a receiver (200), control data may be used with multimedia data to provide a multimedia clip which identifies features of a track, such as artist, song title or lyrics. Identifying data may be communicated with the tracks to allow a user to skip disliked tracks or recover favorite tracks on another programming service stream.

Title: Cutting apparatus for cutting thermoformed plastic sheet
Inventor: SOFRONIE MIRCEA T
IPC: B26D7/18
Filed: 2000-10-06
Abstract: A cutting apparatus usable in conjunction with a thermoforming machine that produces a thermoformed plastic sheet is designed to cut the thermoformed plastic sheet to separate a portion of the plastic sheet from the remainder of the plastic sheet. The cutting apparatus includes a cutting mechanism that moves across the width of the sheet. The cutting mechanism is in the form of a cylinder actuated sheet cutting knife whose operation is controlled in conjunction with the operation of the thermoforming machine to effect cutting of the plastic sheet at desired intervals. The apparatus also includes a hold down mechanism that is operated in synchronism with the operation of the thermoforming machine and the cylinder actuated cutting knife. The hold down mechanism is designed to hold down the thermoformed plastic sheet to thereby facilitate the cutting of the plastic sheet.

Abstract: An object of the present invention is to provide a means for accurately locating fault points by calculating the surge propagation speed at the time of surge identification. The present invention includes a method of calculating surge propagation speed in a fault point location system comprising: substations [1] installed along transmission and distribution lines for sending surge detection time information along the transmission and distribution lines to a master station [2]; and the master station [2] for locating a fault point on the basis of the surge detection time information; characterized in that the surge propagation speed is obtained on the basis of detection times of a surge voltage or a surge current at the first substation positioned adjacent to a fault point along the transmission and distribution line and another substation positioned next to the first substation together with a length of the transmission and distribution line between the first and other substations. Based on the distance between substations [1A and 1B] and the difference of surge propagation time, the surge propagation speed v AB can be computed. Therefore, the surge propagation speed v AB that is obtained can be used as the surge propagation speed v which will be used for identifying the location of the fault point [P]. Moreover, such surge propagation speed is used to identify the location of a fault point, therefore enabling an accurate fault point location under varying conditions such as of transmission and distribution line or weather.

Title: Overload clutch
Inventor: VIAUD JEAN
IPC: F16D9/06
Filed: 2000-11-16
Abstract: A drive shaft and driven chain sprocket are interconnected by an overload clutch embodying a shear pin. The overload clutch includes a first clutch element fixed for rotation with the shaft, a second clutch element mounted on the shaft next to the first clutch element for axial and rotational movement relative to the first clutch element. The second clutch element includes a circular flange disposed against a flat circular surface of the sprocket and coupled for rotation therewith by a shear pin extending through aligned holes in the flange and sprocket. The sprocket is mounted for rotation about a cylindrical shoulder provided on one side of the circular flange of the second clutch element. The first and second clutch elements respectively have positive engaging surface elements that are normally held in locking engagement with each other by a coil compression spring acting between the shaft and the sprocket. After load condition causes the a shear pin to shear, a realignment of holes in the second clutch element flange and the sprocket is achieved by overcoming the force holding the first and second clutch elements in engagement with each other and then rotating the second clutch element relative to the first clutch element and the sprocket.
